WebMay 7, 2024 · Complex carbohydrates, or polysaccharides, consist of hundreds or even thousands of monosaccharides. They include starch, glycogen, cellulose, and chitin. They generally either store energy or form structures, such as cell walls, in living things. Starch is a complex carbohydrate that is made by plants to store energy. WebInsects have a hard outer exoskeleton made of chitin, a type of polysaccharide. Carbohydrates serve various functions in different animals. Arthropods (insects, crustaceans, and others) have an outer skeleton, called the exoskeleton, which protects their internal body parts (as seen in the bee in Figure 8).
